AXLE AND BOX FOR WHEELS.

SPECIFICATION forming part of Letters Patent No. 350,950, dated October 19,1886.

Application filed February 2, 1886. Serial No. 190,611. (No model.)

To aZZ whom it may concern:

Be it known that 1, Louis STEINBERGER, of the city, county, and State of New York, have invented certain new and useful Improvements in Axles and Boxes for \Vheels, of which the following is a full, clear, and exact description.

The invention consists in the construction and combination of parts, as hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 represents a central longitudinal section of a hub embodying my invention. Fig. 2 is a side elevation of the axle. Fig. 3 is an end view of the axle and box, the axle being in section.

A represents an ordinary hub, to which is fitted my improved box,extending through the hub A from end to end and secured thereto in the ordinary or any approved manner. The inner surface of the box consists of two straight bearing-surfaces of different diameters, the smaller short bearing-surface being in the outer end, the remainder being enlarged, as shown. The bearing-surfaces ofthe axle I are made to correspond to the axle-box B that is, smaller at the outer endandlarger at the inner end. From the larger to the smaller bearing part of the axle the same is gradually reduced in size, so that when inserted in the box the space F is formed for the lubricating material. By this construction the axle is strengthened at the inner end, where it receives the most strain, and the lubricating material has easy access thereto.

On the inner end of the box Bis formed an annular shoulder, O, which projects beyond the hub to form a recess for the collar S of the axle, and is beveled oif to deflect the mud, dust, &c., and preventits entrance to the bearing-surfaces.

I am aware that central lubricating-spaces have been formed in axle-boxes; but such spaces have heretofore consisted of recesses formed in the box specially therefor, and the lubricating material is outside of the plane of the axle. In my boxthe lubricating material, being always in the plane of the bearing-surface, flows more readily to the inner end of the axle, which receives the greatest strain.

I am also aware that the projecting end of the box which receives the axle-collar has been beveled off; but such bevel projections have heretofore consisted of a separate piece or thimble, and not cast or formed in one piece with the box, as in my invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination, with an axle-box whose inner surface consists of two straight bearingsnrfaces of diiferent diameters, the larger one being of greater length than the smaller one, ofthe axle I,having two bearingsurfaces of different diameters, and being gradually tapering from the larger to the smaller bearing, whereby a space for the lubricating material is formed, so that the lubricant will always be in a plane with and will readily flow to the bearing-surface of the axle, as set forth.

2. An axle-box for whcels,having formed on its inner end an annular shoulder or projection extending beyond the hub, and forminga recess to receive the collar of the axle, the outer surface of the said shoulder being beveled to detlect the mud, dust, 850., falling thereon, and prevent the entrance of the same to the bearing-surfaces, as set forth.
